3-2 The Slope Formula

A.3b I can calculate the rate of change from a table or two points

Multiple Choice

Which is the correct way to set up slope formula for this table? And, what is the slope for this table?

•  $\frac{11-3}{1-0}$  , 8

•  $\frac{1-0}{11-3}$  , 1/8

Multiple Choice

A line that passes through the points (-7,-3) and (3,-4); what is the correct slope formula and slope for this line?

• $\frac{-7-\left(-3\right)}{3-\left(-4\right)}$ , $m\ =-\frac{4}{7}$

• $\frac{-4+3}{3+7}$ , $m\ =-\frac{1}{10}$

Multiple Choice

Using the Ti-Nspire to calculate slope.

You can use this with two points or even by picking any two points from a table or graph.
